, wheels which are at that time in their zero posi- 7 Claims.

This invention relates to fuel dispensing apparatus, and particularly to fue1 dispensing apparatus in the form of recording pumps particularly adapted for the protection, from fraud, of buyers of fuel dispensed therefrom.

It is an object of this invention to provide means and a method of operation of fuel pumps whereby to issue to each purchaser of gasoline, kerosene or other fuel dispensed therefrom, a ticket recording the exact amount of fuel dispensed to the purchaser, by the pump. in order to protect the buyer from overpayment due to short measure, either intentional and fraudulent, or unintentional and inadvertent.

It isa vfurther object of this invention to provide for the issuance, to each purchaser of fuel from a fuel dispensing pump, of a sales ticket or receipt having registered thereon the quantity zero denoting that the pump indicator was reset to zero before the dispensing operation was begun and to, thus, prevent the purchaser from being charged for a previously registered quantity which he did not receive at the time of his purchase.

It is a further object of this invention to insure that the pump indicator means shall be reset to zero reading after each dispensing operation by providing mechanismv automatically operative,

upon failure so to reset the indicator, to mask or obscure the indicator dial during a succeeding dispensing operation (without resetting of the indicator mechanism) to prevent the operator of the pump from seeing the dial, while carrying out that particular dispensing operation.

It is a further object of this invention to indi' cate on the buyers receipt'ticket that the pump hasfnot been reset to zero before the dispensing y operation has begun, when such is not the case.v

It is a further object 'of this invention to provide for the issuance of a record receipt to a fuel purchaser, which may be retained by him for record purposes.

It is a particular object of this invention to perform the following sequence of operations and to provide means for do g so:

A pump of any conventional type is driven by a motor for pumping gasoline through a meter or equivalent mechanism which actuates an indicator and at the same time proportionately moves -printer wheels to print the same numerical indication as visibly indicated by the indicator. This operation is initiated by lifting the delivery hose, supplied by fluid through the meter, from its hook and the movement of the hook so as to l bring about the initial printing from the printer tion.

As the gasoline or other fuel is delivered, the visual indicator wheels turn and indicate the gallons being delivered and simultaneously the printer wheels are being continuously moved to give a similar indication. Upon the completion of the delivery of the desired amount, the hose is re-hung on the hook which thereby closes the motor switch and stops the delivery of gasoline and at the same time brings about a printing operation from the printer wheels which have the same indication at that moment as the visual indicator has.

No deliveryvof the printed slip has as yet been effected. This is effected by the operation of a manual delivery means which is also the resetter for returning the visual indicator and the printing wheels to initial zero position for another operation. This may be either a severing means as a means of delivery or it may be a movement of the strip to `a new position so that it can be torn off as preferred. I

By the foregoing operation of the mechanism of this invention, the quantity of fuel flowing performs a dual operation of visually indicating the quantity of fuel delivered and at the same time of providing means for recording the state of the indicator at the beginning and end of the fuel delivery operation.

These and other objects and advantages will appear from the following description taken in connection with the drawings.

Formerly, in the operation of conventional fuel dispensing pumps, it was possible for the operator to begin a fuel dispensing operation without resetting the pump indicator to zero and thus to cause to be registered upon the pump indicator an amount in excess of the actual amount of fuel dispensed to the purchaser. This enabled the operator of the pump to charge the purchaser, fraudulently, for an amount of fuel in excess of the amount actually received by the purchaser.

According to the principles of this invention, this fraudulent practice is prevented by the provision of means, which may take the form of an attachment to known forms of pump structures, or which may be built therein, as a part thereof, for printing and issuing a receipt ticket for each dispensing operation, having thereon the original and final settings of the pump indicator, by means of which the buyer may carefully check the amount of fuel for which he is charged.

The mechanism is preferably provided with means connecting it to the hose hook of the Immp in such manner that the position of the printing of the starting quantity on the receipt ticket may not properly occurl unless the indicator of the Dump has been reset to zero before the particular dispensing operation, whereby the improper location of the designation ofthe original quantity registered by the pump, or the absence of the quantity 0 0 from the proper place on the `previously resetting and shutter operating means is provided withJan forked extremity receipt ticket may, at once, warn the purchaser of fraudulent, inadvertent or improper operation of the pump by the operator. v

Furthermore, the mechanism is so connected tc the shutter operating means that the shutters are placed over the indicator dials of the pump whenever a dispensing operation is begun without the pump indicating mechanism to zero to thus prevent the pump operator from observing the dial and thus estimating the quantity delivered b'y the pump. Referring to the drawings 'in detail, in Figures l. to 4 inclusive, we have shown a conventional form of motor operated pump with the principles of this invention applied to the indicator means thereof. The details of the conventional internal structure of the pump are omitted in the interest of olearness. The casing of the illustrated pump comprises a pedestal having extending upwardly therefrom a front side wall 2, a rear side 1wall 3, a right side wall 4 and a left side wall 5. The right and left side walls, 4 and 5, are preferably formed of the same sheet material which forms the top wall 8l therebetween, as shown in Figures 1 and 3. The front wall 2 and the rear switch I8 and-cause the pump operating motor I1 to be started.

formed integrally wall 8 are preferably provided with window u means 1 for providing vision of the front and rear dial plates. The front and rear dial plates are provided with suitable apertures which cooperate with numeral-carrying indicator drums for indicating the amount. of fuel dispensed by the pump at a particular time during a dispensing operation and each dial plate is also provided with a grand total aperture cooperating with register meansindicating the total gallonage dispensed by the pump.

In the form of pump let 8 extends outwardly from pump casing hose serew-threadedly attached thereto. Adjacent the hose outlet 8, the left side of the casing inwardly offset portion from which extends outwardly,`through a suitable' slot therein, the outer end I0 of the pump hook or pump hook lever 9, which is pivoted at I2 to a bracket or ear I8 extending inwardly from the left side wall 5 of the casing. The pump hook or 9 has the inner end portion illustrated, the hose outthe left side of the when the hose |4 thereofwill be swung upwardly, and whenD the hose nozzle is removed from the outer end vof the pump hook lever 9, the outer end I0 thereof may be manually thrust upwardly to swing the inner extremity I4 thereof downward y.

In order that the |5 has the upper end thereof pivotally secured to the inner end portion lower end thereof operatively secured in suitable manner to the control switch I6 ofthe pump operating motorll. Thus,when the hose nozzle is hung upon the outer end I0 of the hose hook, the link I5 is drawn upwardly to open the motor switch I6 and stop'the motor I1. Likewise, when the hose nozzle is removed from the outer end II) of the hose hook or hose hook lever 9,'the outer end I0 thereof may be manually thrust upwardly to thrust the link I8 downwardly to close and is adapted to have the pumpinwardly into the pump casing of the lever 9 and the pump-hook lever 9 shall cony `trol thestarting and stopping of the pump, a link clearly described,

'bank of indicator drums,

ignated 82, indicate fractional lon, while the central forward and rear drums inclusive, while y the righthand forward drum and lefthand rear designate gallons from l0- By means hereinafter'Y more Extending outwardly from the right side wall I of thepump casing is the shaft I8 having the lever I9 rigidly secured at its outer end provided at one end with the handlel 20. By engaging the handle 20, the pump operator, subsequent to .the completion of a dispensing operation, may rotate the shaft I8 .to reset the indicator drums of the pump to the zero position. y Y

Disposed between the spaced oppositely disposed dial plates in the pump casing isan indicator mechanism casing, generally designated 2|, which is positioned, as indicated in dotted lines in Figures 3 and 4, and which, as shown in Figures 5 and 6, encloses the indicator drums. As shown in Figures 5 and 6, the plate 22.forms the inner end wall of the casing 2| which is disposed toward the left side wall 5 of the pump casing. of the casing 2| is formed by a similar plate 22a.- The plates 22 and 22a. are secured to the body of screws. as shown hand end, the casing 2| has a vertical wall ,28 therein, and spaced inwardly of the casing from the right end portions of the walls thereof.

Rigidly secured in the pump casing to the right of the indicator casing 2| is the casing 24 which encloses the receipt ticket printing, severing and issuing means which comprises a part of this invention. At the right side, closed by a cover plate 25 which is suitably seand side walls thereof. Integrally formed with the top, bottom and side walls of .the easing 24 is the inner vertical wall 28 which is disposed in spaced relation and in parallelism with the wall 23 of thev indicator casing 2|. f

Extending ving 2l is the attaching flange 21 from the inner side wall of the caswhich is secured by means of bolts 28 (Fig. 6) to the right-r hand end of the as shown in Figures 5 and 6. A suitable aperture is provided in the right side wall 4 for providing access to the cover plate 25, the aperture being closed by a suitably removable plate 4a which closes theaperture in the right side the pump casing (Fig. 2)

In the casing 2| disposed toward the left or inner end thereof, in inwardly the end plate 22' and in parallelism with the wall 23, is a wall 23a. Supported forrotation in the casing 2|, at the rear side thereof by the walls 29 and 23a, is a shaft 39 which supports the rear as shown in Figurer 6. A similar shaft 3| is vlikewise supported for rotation at the forward side of the casing 2|, and this shaft extends rightwardly into the casing 24, as shown in Figures 6,"1 and 8, for a purpose which will hereinafter more clearly. appear.

As shown in Figures 5 and forward drurri and the lefthand rear drum,

portions of a gal- 83 designate gallons drum,l designatedl 94, to inclusive.

fthe drums v32 rotate simultaneously, together,in synchronism, hile the same the drums-88 and rotatable resetting in Figure 5. 'At its right the casing 24 is wall 4 of spaced relation tov 6, the righthand desbetween the drums 34 in order that the same amount may be registered by the dial plate at each side of the pump casing. Such operative connection is provided between one set of drums 32, 33 and 34, that a full revolution of the drum 32 must occur to cause one-tenth of a revolution of the drum 33, while a complete revolution of the drum 33 must occur to cause one-tenth of a revolution of the drum 34.

The meter mechanism of the pump is conventional and, as shown in Figure 12, the shaft 36 thereof has a tubular connector member 31 pinned thereto by means of the pin 38. This tubular connector member 31 is connected by means of the shear pin 39 to the shaft 40 which is thus driven directly from the meter 35. In case of obstruction or excessive binding in the indicator mechanism, the shear pin 39 will be severed, to break the drive connection between the shaft 36 of the meter and the shaft 40 and thus permit the meter 35 to operate independently of the indicator mechanism and prevent breakage, or other damage to the indicator mechanism.

Referring again to Figures and 6, it will be seen that the shaft 40 extends vertically upwardly through the lower wall of the casing 2| and has rigidly secured to the upper end thereof the bevel gear 4|. This bevel gear 4| meshes with the bevel gear 42 which is pinned to the shaft 43. The shaft ported at the right end in the casing 2|, and the left end thereof is supported by the overrunning clutch mechanism 44 secured to the end thereof.

Also connected to the overrunning clutch 44 is a shaft 45 which is rotatably supported by the wall 23a and the bracket 46 (Fig. 5). Rigidly secured to the shaft 45 between the wall 23a and the bracket 46 is the pinion 41 which meshes with the gear 48. The gear 48 is rigidly secured to the left end of a shaft 50 which has one end rotatably supported in the wall 23a, while the other end thereof is supported by means and in a manner which will hereinafter more clearly appear. The gear 48, as hereinafter more clearly described, meshes with the drive gear of the rearmost indicator drum 32, as shown in Figure 6.

'I'he means for transmitting the drive from the rearmost indicator drum 32 to the rearmost indicator drum 33. and from Vthe rearmost indicator drum- 33 to the rearmost indicator drum 34, as Well as the drive between the forward and rear drums 32, the forward and forward and rear drums 34 are also hereinafter most clearly described.

Also driven from the shaft 43 is the indicator mechanism for indicating on the forward dial plate the total gallonage dispensed by the pump. This means comprises, as shown in Figure 5, a pair of spaced brackets 5| having rigid support on the bottom wall of the casing 2| and rotatably supporting the shaft 52 having at its end a bevel gear 53 which meshes with the bevel gear 54. The bevel gear 54 is rigidly secured to the outer and lower end of the inclined shaft 55 which has likewise rigidly secured to its upper and inner end a bevel gear 56 which meshes with a gear 51 rigidly secured to the righthand end ofthe shaft 43 (Fig. 5)

Mounted on the shaft 52 between' the brackets 5| are a plurality of indicator drums which are suitably driven in conventional manner from the 'shaft 52 so that the righthand drum must rotate ten. revolutions to cause one revolution of the 43 is suitably rotatably suprear drums 33 and the Y ten full revolutions to cause second, and the second must rotate ten revolutions to cause one full revolution of the third. while the third must rotate ten revolutions to cause one full revolution of the fourth, the fourth must rotate ten full revolutions to cause one full revolution of the fifth, and the fth must rotate one full revolution of the sixth. The righthand drum, therefore, registers gallons in tenths, the second in units, the third in tens, the fourth in hundreds, the fifth in after more clearly appear, the masking plate 5| a is provided, which is normally disposed over that portion of the indicating dials which are aligned with the side aperture in the front indicator plate. This masking plate 5|a is provided with inspectors may have access to the grand total, according to the principles of this invention.

It will thus be seen that when the hose nozzle is supported on the outer end I0 of the hose hook lever 9, the motor will be inoperative, as will also the pump, and that when the outer end 0 of the hose hook tion.

AS shown in Figure 6 and as briefly described above, the rear indicator drums 32, 33 and 34 are driven from the gear 48, and from these rear indicator drums 32, 33 and 34, means of syncator drums 34 in such manner that the forward indicator drums 32, 33 and 34 are driven synchronously from the gear 48.

As also described above, the shaft 3| extends on the shaft 3|. Superposed on this sleeve 58 for rotation thereon is the sleeve 59 which has the left end thereof rigidly secured to the forward indicator drum 33. Superposed on and rotatable the third or outer sleeve 6U which has the forward indicator drum 32 rigidly secured to its left end.

Rigidly secured to the right end of the outer sle'eve 60 for rotation with this sleeve and with the rigidly attached indicator drum 32 is the 62. Disposed to the right of the type disk member 62 and rigidly secured to the end of the intermediate sleeve 53 Athird rotary type is rigidly attached to the right which rotates with the indicator drums 84 for registering tens, is farthest from these members, and that the type disk member 82, which rotates with the indicator drums 82, is closest these members, and that the intermediate type disk member 88, which rotates with the intermediate indicator drum 38 for indicating units, is disposed l intermediate the fractional type disk member 82 and the tens type disk member 84.

Journaled at its inner endin the wall 28 of the casing 24 and at its outer end in suitable bearing means provided in the cover plate 25 is the freely rotatable shaft 85 which has secured thereon for limited rotation the printing roll 88 and its drivegear 81 which is pinned thereto.

u The printing roll 88 may be termed a type roll, because it is provided with a type facing adapted, in 4a manner hereinafter more clearly described. for printing an impression on a paper strip or web passing thereover. The manner'of securing the printing roll to the shaft 85 for limited free rotationnis shown in Figures 9 and l0, wherein it will be seen that a pin member 88 vextends through the shaft 85 and has its ends, at oppo-v site sides of the shaft 88, disposed in arcuate recesses in the roll 88 in such manner that a predetermined amount of relative rotation between the roll 88 and shaft 88 is Permitted.

Rigidly secured in spaced relation to the wall 28 and in parallelism therewith is a bracket plate 89, as shown in Figures and 6. A shaft 18 is disposed adjacent and in parallelism with the shaft 88 with one end thereof journaled in the bracket 88 and the other end thereof suitably iournaled in means provided in the cover plate 25. Rigidly secured to the shaft 18 for rotation therewith is the resilient-pressure roll member 1| of rubber or other suitable material, having rigidly vpinned thereto. adjacent one end, a gear 12 which mesheswith the gear 81 on the printing roll 88, and pinned tothe gear 12 is a finger member 18. Pinned-to the shaft 88 for rotation therewith isfthe pinion 14 to which is' pinned the cam follower member 15 having the antifriction rollerr18 at its outerend.

The wall 28 is provided with a boss 11a. to which is screw-threadedlsr secured a stud 11 upon which is rotatably secured at the outer end of the stud 11 the driving gear 18, to which driving gear 18 is pinned at its inner side the mutilated gear 418. The mutilated gear 18 is in augment with the pinion 14 and cooperates therewith in a manner hereinafter more clearly described, to,

cam member 88 in counterclockwise direction, as seen in Figures 8 and 18. p

Upon rotation of the driving gear 18, mutilated gear 18 and cam 88, it will be seen that, as the teeth on the mutilated gear 18 engage the teeth of pinion 14 for rotation of the shaft 85,

i' the roller member 18 engages the notch 8| in the cam member 88 to permit further counterclockwise rotation of the mutilated g'ear 18 and the cam member 88 and consequent clockwise rotation of the shaft 85 for one complete revolution. Assoon as the `shaft 85 has rotated through one complete rotation, the roller 18 will engage the circular peripheral portion of the cam member 88 to prevent further clockwise rotation of the shaft 85, as seen in Figure 8. This means insures that the printing roll 88 and the pressure roll 1|,uwhich is geared therewith through gears 81 and 12, shall rotate a predetermined amount to cause ,a predetermined amount of feed of the paper strip or web and the adjacent carbonweb (hereinafter described) disposed therebetween,

and to cause to be printed upon the paper web a full impression of the type on the printing roll 88. This impression will preferably take the Vform illustrated in Figure 32, save that the numerals appearing in parallelism with the words initial and final will not be printed thereon predeterminedly rotate the shaft 85 through one complete rotation in order that a full revolution of the type face oft he printing roll 88 may occur upon each full rotation` of the mutilated gear 18. Plnned to the inner side of the mutilated gear 18 for rotation therewith is a rotary cam'member 88 having its peripheral 'portion provided with a suitable notch 8i which cooperates with the roller 18 on the cam follower member 15 in a manner which will hereinafter more clearly ap- Pe L Y It will be clearly seen from the above that the driving gear 18,'mutilated gear 18 and cam member 88 rotate together, and the means for rotating the driving gear 18 comprises the reset gear 82 which meshes with the driving gear 18 and which is pinned to the above described reset shaft i8 in such manner that rotation of the shaft I8 for resetting the indicator drums will cause the reset gear 82 to rotate in clockwise direction, as seen in Figure 8, to cause counterclockwise rotation ,of drive year 18, mutilated gear18, and

V 1I, the paper and carbon webs by the above described'rotation of the printing roll 88.

In Figure 1, the carbon web, which is continuous, is designated 83. At the upper end, above the printing roll 88, this web or continuous strip 83 is supported by a freely rotatable roher 84 and arcuate stationary guide plate 85 immediately below the type disk members 82, 88 and 84. Freely rotatable rollers 85 and 81 support the web 88, while the lower end .portion thereof is supported by the freely rotatable roller 88 in con- Junction with the freely rotatable guide roller 88. The guide rollers 84, 88, 81, 88 and 88 are all pivotally supported by the casing having their pintles rigidly secured to the wall 28 and the inner lower wall of the casing 24.

The paper, in the form of a web 88, is wound Y in a roll upon the center member 8l which rotates freely on the pintle stud 82 ,which is rigid with the wall 28 and which extends outwardly therefrom to provide means for supporting the cylindrical center member 8l and the paper wound ther-ecm From the roll, the paper web 88 extends upwardly to the flanged arcuate guide plate 88 about which it passes and by which it is supported and it then extends over the flanged arc,

uate guide plate 84, and thence downwardly between the printing roll 88 and the resilient pressure roll 18.V The paper web 88 and endless carbon web 88 are thus maintained in close contact between the printing roll 88 and the pressure roll 1i.

'Below the printing roll 88 and pressure roll pass downwardly between type disk members 82, 88 and 84 and a I* reciprocable platen member which is actuated at predetermined times to press the adjacent paper and carbon webs against predetermined portions of the type disk members 82, 88 and 84 'forprintins the initial and final ceipt ticket.

After passing through the quantity printing zone, the carbon web 88 passes about the guide rollers 88 and 81while the free end of the paper web passes downwardly between the forward the rear ticket guide plate 88. n

forward ticket guide ticket plate 88 and Below and adjacent the quantities upon the re mined lengths from the web 90 to form tickets as shown in Figure 32. From the severing zone, the paper passes between a pair of ticket guide plates and |02 into a ticket issuing receptacle |03 (Figs. 2, 3 and 8), where it may be withdrawn through an aperture provided in the right side wall 4 of the pump casing.

The means for causing the rolls 66 and 1| to be predeterminedly advanced, within each feeding cycle, formoving thestrip 90 a sufiicient amount between the beginning of a dispensing operation and the end of the dispensing operation in order to cause advance of theticket from the initial position wherein the initial portion of the ticket is disposed in the printing zone (formed by the alined portions of the type disk members 62 63 and -64 and the cooperating reciprocable platen member) to the ilnal position wherein the final portion of the ticket is disposed in the printing zone, includes the cam carrier member or cam bar |04. The cam bar |04 also predeterminedly causes reciprocation of the platen member for causing printing of the initial and final quantities in thefinitial and final portions of the ticket and also the reciprocable severing blade which cooperates with the stationary cutter blade 91. I

As shown particularly in Figure 5, the cam bar |04 which is suitably guided for vertical reciproeating movement in the casing 24 has an upper loop portion which is offset (to the right in Fig. 5) from the lower portion thereof, which lower portion, at its lower end, has thereon a pintle member |05 to which is pivotally secured the outer end of the lever |06 which has its other or inner end rigidly secured to the rock shaft |01. The rock shaft is pivotally supported at one end by suitable bearing means formed in the inner wall of the casing 24 and at the other end by bracket meansr|08 secured 'to the lower side of the indicator casing 2| (Fig. 5). At the end 'of the rock shaft |01, opposite that to which the lever |06 is secured, is rigidly secured the arm |09 which has a hook portion at its outer end disposed in the inner forked extremity |4 of the pump hook lever 9.

In Figure 5, the parts are shown in the position taken when the hose nozzle is supported by the outer end I0 of the pump hook lever 8. The corresponding position of the pump hook lever 9 is indicated in full lines in that gure. When the outer end of the pumphook lever I is swung upwardly, as above described. to initiate operation of the pump, the pumphook lever will take the dash line position shown in Figure 5, whereby the arm |09 and lever |06 will be swung rearwardly, as seen in Figure 5, or in clockwise direction as seen in Figure 7, to cause the cam bar |04 to be moved downwardly. Naturally, when the hose nozzle is replaced on the outer end I0 of the pump hook lever 9, the pump hook lever 6 will be swung from the dash line position of,

Figure 5 to the full line position therein, whereby the cam bar |04 will be reciprocated upwardly to the original position, as shown in Figures 5 and 7.

The means for causing the above-described feeding of the ticket so that the portion of the ticket will be disposed in the printing zone at `the end of the dispensing operation comprises the block ||0 which is rigidly secured to the upper end of the loop portion of the cam bar |04 on the outside, and to which is pivotally secured a finger member I I which Ais spaced from the block ||0 by means of the spacer H2. Swinging movement of the finger member I in counterclockwise direction, as seen in Figures 7, 8 and 9, is limited by the pin ||3 which extends outwardly from the block I0 for that purpose. The finger member III is aligned with the above described 1 linger member 13 in such manner as to engage the finger 13 to cause counterclockwise rotation of the shaft 10, as seen in Figures 7, 8 and 9, upon upward reciprocation of the cam bar |04, caused by return of the hose nozzle to the outer end Il of the pump hook lever 9, as above described.

'I'his counterclockwise movement of the shaft 10 will cause movement of the printing roll 66, free of the shaft 65, from the position shown in Figure 10 to that shown in Figure 9. In the latter figure, the cooperation of the finger members III and 13 is shown. As is shown in Figure l0, when this movement occurs, the shaft 65 is held against rotation by engagement of the roller member 16 of the cam follower 15 with the circular peripheral surface of the cam Il. 'I'he pin 6I thus cooperates with the arcuate recess in the printing roll sito limit the relative rotary movement between the printing roll 66 and the supporting shaft 65. 'I'he linear advance of the lticket between rolls 66 and, 1| is thus predeterminedly limited in such manner that upon the above cooperative engagement of finger members 13 and III, the ticket will be fed an exact predetermined distance equal to the distance between the gures representing the initial" and final quantities, as shown on the ticket in Figure 40.

Due to the fact that the finger member may freely rotate in vclockwise direction, as seen in Figures '1, 8 and 9, upon downward movement of the cam bar |04, it will pass the finger mem' ber 13 without, in any way, affecting the position ofthe finger member 13 or the rolls 6I and 1|. The platen means for cooperation with' the type disk members 62, I3 and 64 comprises an elongated platen bar |I4 having, at one end, a

' yticularly in Figures 7, 8 and 11.

platen facing member ||6. The platen facing member may be formed of any suitable material, either resilient or non-resilient, but is preferably formed of a material similar to that from which the roll 1| is formed and having like resiliency. The platen bar ||4 is supported for reciprocation toward and from the type disk members 62. 03 and 64, and, at the end opposite the head III. is provided with a bifurcated or forked portion ||1 which straddles the reset shaft I6, as shown par- The under side of the platen bar I I4, adjacent the head I Il, is provided with a suitable slot which receiv the upper end of a leaf spring member lll which has the lower end thereof rigidly secured in a block Ill which is rigid with the casing 24.

As above described, and as shown in Figure 7, the paper web and carbon web Il Dass between the platen facing member I and the aligned portions of the rotary type disk members 62, 6I

and 64. The figures on the members' 62, 63 and I4 which are in alignment with the member III always correspond with the gures displayed by the indicator means, because of the above dezero. The quantity zero will be printed at that scribed connection through sleeves I3, 33 and 30 of the respective type disk members with.thelr correspondins indicator drums.

Thus, when the indicator drums `indicate the quantity zero, the corresponding numerals of the type disk members 02. 63 and 04 will be disposed in alignment with the member H6. This, of course, occurs when operation of the pump is begun by swinging the outer end of the pump hook lever 3 upwardly to draw the cam bar |04 downwardly, as above described. At this time, the downward movement of the cam bar |04 causes the platen bar I i4 to be moved away from the type disk members or to the right, as seen in Figures 1, 8 and 11, and then released for travel toward the type influence of spring H3.

The means for causing the above-described retraction and release of the platen bar ||4 for forward or advance movement by the spring .member 8, upon downward movement of the cam bar |04 for printing the initial quantity on the ticket, comprises a cam member |20 on the cam bar |04 and cooperating iinger means |2| on the platen bar ||4. The cam bar |04 also Ecarries a second cam member |22 which cooperates, upon the opposite or upward return movement of the cam bar |04, with finger means |23 on the platen bar I4. The inner vertical part of the loop portion of the vcam |04 is designated |04a (Figs. 5, 8 and 11), while the outer part thereof is designated |04b. The cam members |20 and |22 are secured to the oppositely facing innersides of the loop portion with the cam member |20 secured to the part |04a and the cam member |22 secured to the part |04b thereof.

The finger members |2| and |23 are pivotally secured to the platen bar ||4 by means of the pintle member |24. Each end of the forked portion ||1 of the platen bar ||4 has a `pin |25 extending outwardly therefrom and the upper pin |25 has one end of' a tension spring |20 secured thereto, while the opposite end of this spring |26 is secured to a pin |21 which is similar to the pins |25 and similarly disposed with respect to one end of the finger member |2|. The lower pin |25 has one end of the tension spring |28 secured thereto. The opposite end of the spring |28 is secured to a pin |23, similar to the pin |21, and secured to the end of the finger member |23 in the same manner in which the pin |21 is secured to the finger member I2 As shown in Figures 8 and 11, the springs |26 and |23 normally urge the rear ends of the finger members. |2| and |23 inwardly to the reset shaft i3 which limits inward movement thereof. The finger member |2| has at its opposite end a rearwardly and upwardly inclined surface |2 la which is adapted, upon downward movement of the cam bar |04, to be engaged by a similarly inclined surface |20a on the cam member |20. This tends to swing the finger member |2| in counterclockwise direction, but as this swinging movement is prevented by abutment of the rear end of the finger member |2|, with the reset shaft l0, the platen bar ||4 is moved rearwardly or away from the type disks until the cam member |20 has passed the surface |2|a, at which time the platen. bar ||4 will be released for forward movement under the control of the spring member I3. At this time, the initial portion of the ticket will be disposed in the printing zone, lithe indicatorvmechanism has been reset to l bar |04, the dispensing disk members under the l portion of the ticket. e

After this downward movement of the cam operation is accomplished before upward movement of the cam bar |04 occurs due to depression of the outer end I0 of the pump hook lever 0 by placing the hose nozzle thereon. The cam member |22, which is secured to the part |04b of the cam bar |04, is provided with a forwardly and upwardly inclined surface |22a which is adapted, upon upward movement of the cam ilarly disposed inclined end 'surface |23a on the finger member |23 (Fig. 11). This engagement of the surfaces |22a and |23a tends to swing the finger member |23 in clockwise direction, as seen in Figuresl 8 and 11, but engagement of the rear end of member |23 with the reset shaft I8 prevents this movement, whereby the cam bar ||4 rearwardly or away from the type disk members until the cam member |22 passes the finger member |23, whereupon the platen bar ||4 will be released for forward printing movement under the force of the spring member H8. This printl ing action, of course,l takes place subsequent to completion of the dispensing operation and subsequent to the advance of the ticketby engagement of finger members and 13, as above described, to advance the ticket in such manner that the final portion thereof will be disposed in the printing zone when this printing action oc curs. Necessarily, the quantity printed in the flnalgspace of theticket will, of course, correspond with the ilnal reading of the indicator mechanism.

Thus, as described above, downward movement of the cam bar |04, when the initial portion of the ticket is disposed in the printing zone,

causes retraction and release of the platen bar ||4 for printing the initial quantity in the appropriate portion of the ticket. Subsequent upward or return movement of the cam bar |04, after the ticket has been so fed that the final portion is disposed in the printing'zone, causes retraction and release .of the platen bar ||4 for printing the final quantity at the appropriate point on the ticket.

Means is provided for predeterminedly severing each printed ticket from the strip or web 3l,

which means includes, as above described, the stationary cutter blade or severing blade 31. Co-

operating with this stationary cutter blade 31 is a reciprocable cutter blade |30 which is secured by screw means |3| to a step provided at the forward end of the head |33 of the reciprocable cutter bar |32. Suitable guide means is provided for guiding the/ head portion |33 of the cutter bar |32 in its reciprocation, and the opposite or rear end of the cutter bar |32 has a forked or bifurcated portion |34 which straddles the cutter operating shaft |35 in thesame manner in which the bifurcated or forked portion ||1 of the platen bar ||4 straddles the reset-shaft-l |8. This cutter operating shaft |33 is suitably journaled in lthe casing 24 with one end thereof supported by a boss provided on the wall 20, and pinned to the shaft |35 for rotation therewith is a gear |33 which meshes with the reset gear 32. Also pinned to the cutter operating shaft |35, adjacent the forked or bifurcated end portion |34 of the cutter bar |32, is a cam member |31 which is adapted to cooperate with a cam follower roller |38 which is journaled on the pin |39. The pin |33 is rigidly secured to one side of the cutter bar |32,
